# springboot炖dubbo-client
2+
### 1. 先睹为快
3+
### 2. 实现原理
4+
#### 2.1 新建项目
5+
#### 2.2 创建maven目录结构，以及pom.xml文件
6+
#### 2.3 pom.xml文件中加入依赖
7+
```xml
8+
<parent>
9+
<groupId>org.springframework.boot</groupId>
10+
<artifactId>spring-boot-starter-parent</artifactId>
11+
<version>2.0.5.RELEASE</version>
12+
<relativePath/>
13+
</parent>
14+
```
15+
#### 2.4 pom.xml文件中加入springboot-starter依赖
16+
```xml
17+
<dependencies>
18+
<dependency>
19+
<groupId>com.oven</groupId>
20+
<artifactId>springboot_dubbo_common_api</artifactId>
21+
<version>${project.version}</version>
22+
</dependency>
23+
</dependencies>
24+
```
25+
#### 2.5 pom.xml文件中加入maven-springboot打包插件
26+
```xml
27+
<build>
28+
<plugins>
29+
<plugin>
30+
<groupId>org.springframework.boot</groupId>
31+
<artifactId>spring-boot-maven-plugin</artifactId>
32+
</plugin>
33+
</plugins>
34+
</build>
35+
```
36+
#### 2.6 开发启动类
37+
```java
38+
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
39+
import org.springframework.boot.SpringApplication;
40+
import org.springframework.boot.autoconfigure.SpringBootApplication;
41+
42+
@EnableDubbo
43+
@SpringBootApplication
44+
public class Application {
45+
46+
public static void main(String[] args) {
47+
SpringApplication.run(Application.class, args);
48+
}
49+
50+
}
51+
```
52+
#### 2.7 开发测试接口类
53+
```java
54+
import com.oven.service.DemoService;
55+
import org.apache.dubbo.config.annotation.Reference;
56+
import org.springframework.web.bind.annotation.RequestMapping;
57+
import org.springframework.web.bind.annotation.RestController;
58+
59+
@RestController
60+
public class DemoController {
61+
62+
@Reference(version = "1.0.0")
63+
private DemoService demoService;
64+
65+
@RequestMapping("/test")
66+
public String test(String name) {
67+
return demoService.sayHello(name);
68+
}
69+
70+
}
71+
```
72+
#### 2.8 编辑配置文件
73+
```properties
74+
server.port=8081
75+
dubbo.application.id=client
76+
dubbo.registry.address=zookeeper://172.16.188.194:2181
77+
```
78+
#### 2.9 编译打包运行
79+
